By understanding past performance, you can make more informed financial decisions regarding your mortgage and investment strategies.

Step 1: Understand the Problem with Averages

• Averages can be misleading when it comes to financial decisions.

Step 2: Analyze Historical Market Data

Step 3: Evaluate the Test Methodology

• Understand how the historical backtest was conducted.
• Recognize the criteria used to compare mortgage payoff versus investing.
• Pay attention to assumptions made during the analysis, such as interest rates and market conditions.

Step 4: Review ISA Results

• Examine how Individual Savings Accounts (ISAs) have performed historically.
• Assess the benefits of tax-free growth in ISAs when compared to mortgage interest savings.
• Evaluate scenarios where investing in an ISA may be more advantageous than paying off a mortgage.

Step 5: Consider Different Mortgage Sizes

Step 6: Investigate Pension Outcomes

• Understand how these allocations can affect investment growth and mortgage payoff timelines.
• Evaluate the risk levels associated with various investment strategies.

Step 8: Identify Key Considerations

• Reflect on personal circumstances that may affect your decision (e.g., financial stability, risk tolerance).
• Assess the importance of liquidity and access to cash when choosing between paying off a mortgage and investing.
• Consider the potential need for future cash flow and how it relates to your mortgage.
